PRINTING ATTACHMENT FOR PAPER-BAG MACHINES.

.To a/ZZ whom it may concern.-

Be it known that I, EDWARD STANLEY, of Bridgeport, in the county ofMontgomery, State of Pennsylvania, have invented certain new and usefulImprovements in Printing Attachments for Paper-Bag Machines, of whichthe following is a speciiication.

The purpose of the invention is to provide a new, simple, and efcientmeans for print= ing, marking, 01 numbering completed paper bags as theyare delivered fromthe machine.

In the accompanying drawings, Figure l is a sectional view showing thedelivery-rolls of a bag-machine and the printing-rolls which constitutemy improved attachment; Fig. 2, a rear or end View of the same; Fig. 3,a view of the ink-fountain detached; and Fig. 4 shows in detail the edgeof the type-carrying roll in section and elevation.

A B represent the delivery-rolls of any ordinary bag-machine, and X mayrepresentl a paper bag passing from the delivery-rolls through theprinting-rolls C D. C is the upper friction-roll, which may have asurface covered with rubber, cloth, or any suitable material to renderit more or less elastic.

D is the lower type-carrying roll, operating in conjunction with theroll C and driven at the same speed that the bag X is traveling, andmakes one revolution to each bag. In the face of this roll a transversetangential recess is formed, within which a type-holding segmental plateD is secured by a screw CZ.

E is the type-block, having thereon the numberszor letters to be printedupon the bag. In the drawings it contains the matter Standard 2. It isseated in a socket in the plate D and secured by a screw d', passingthrough the under side of the plate.

F is the inking-roll. It is of the same diameter and is geared to runwiththe roll D. A central transverse hole or passage f is formed in it,and within this hole the inkingfountain G is secured in such positionthat its pad g will make contact with the typeblock E as the rollsrevolve.

The body of the ink-fountain is composed of a tube G', screw-threaded ateach end. One end is closed by a solid cap G2, and the other l receivesan open face or ring cap G3, the open ing in the cap being preferablyabout ,the same width as the bore of the tube. A piece of cloth, felt,or other suitable porous or fibrous material g, placed within thering-oap G3, is clamped at its edges between the cap and the end of thetube. IVithin the tube G is a closely-fitting cup-shaped plug II, havinga number of apertures 7L in its head, and between the plug and the clothg a suiiicient number of disks or pieces of woolen cloth or othersuitable material g are placed. In filling the fountain with ink the cupHis pressed outwardly against the cloth g g and the tube is filled withink, and the end of the tube is then closed by the cap G2, which isprovided with a Washer II. The centrifugal force developed by therotation of the roll keeps the ink against the pad, and the quantity ofink upon the surface of the pad may be regulated by varying the numberof cloth or fibrous disks g.

NVith this attachment bags may be marked with as great rapidity andeasev as they can be delivered from the rolls A B. The face of the pad gis by the centrifugal action kept supplied with ink, and once in eachrevolution the pad inks the type-block, and once in each revolution ofthe rollD a bag is printed and delivered from the machine.

I claim as my inventionl. The combination of the type-carrying roll, theinking-roll having a passage therein transverse to its axis, and thevremovable yink-carrying tube'arranged in said passage, and having aninking-pad adapted to supply ink to the type, substantially as setforth.

2. 'Ihe combination, with a roll F, having a transverse central passagef formed therein, of an ink-fountain secured in said passage, consistingof a tube having a removable cap G3 and a pad g.

3. In combination with a rotating roll or support, an ink-fountainconsisting of a body or tube G', having a removable ring-cap G3, aninterior perforated plug H, and adapted to hold the cloth or fibrousmaterialg g', substantially as set forth.

4t. In combination with a rotating roll or support, an inkefountan G,consisting of a In testimony Wheleof I have hereunto subtube G', a solidremovable cap G2 closing it scribed my name. at one end and a removablel'inH-eap G3 u )on T the other end7 the perforated pllg H, andltheEDVARD STANLEX' 5 cloth or brous material g g', forming the Witnesses:

pad and interposed between the plug and the A. R. PLACE, rng-cap- E. L.IIALLMAN.
